Among the species discovered recently in Papua New Guinea were tiny bear-like creatures, frogs with fangs, fish that grunt, kangaroos that live in trees, and what is probably the world’s largest rat (with no fear of humans). Scientists from Britain, the United States, and Papua New Guinea announced the findings in September, among more than 40 new species from a jungle habitat a half-mile deep inside the centuries-dormant Mount Bosavi volcano crater.
